His in-game persona, known as the Demon Lord, was defined by his overwhelming gear and high skill level.

The source material highlights his transition from a solitary online existence to a celebrated figure in the gaming community, emphasizing the disparity between his real-life isolation and his powerful digital identity.

Diablo, Rem, and Shera become adventurers in Faltra but face an elf trap

Seeking financial stability, Diablo, Rem, and Shera take on roles as adventurers within the city of Faltra. During their very first quest, the trio encounters a dangerous situation orchestrated by elves. These elves intend to force Shera to accompany them back to their territory. The group finds themselves ensnared in a trap designed specifically to separate Shera from her companions. This initial mission quickly turns into a confrontation as the adventurers must navigate the immediate threat posed by the elves' abduction attempt while trying to survive the encounter.

Diablo and Shera depart for a new quest while Rem remains in the city as the Fallen army prepares to invade.

Diablo and Shera prepare to embark on another quest, leaving Rem behind to guard the city. Meanwhile, an army of Fallen gathers its forces, readying itself for an imminent invasion. The narrative focuses on the impending conflict as the heroes split their duties, with the protagonists heading out while Rem stays to defend their home against the approaching threat.

Rem battles Fallen intruders while Diablo confronts the enemy army and leader Edelgard alone.

Rem engages in combat against Fallen forces that have successfully bypassed the town's defensive barriers. Simultaneously, Diablo stands alone against the entire Fallen army and their commander, Edelgard. The narrative highlights the separate confrontations faced by these two characters as they defend against the invading threat. Rem focuses on the infiltrators who breached the perimeter, while Diablo directly opposes the main military force and its leader. This sequence emphasizes the dual nature of the conflict, with each protagonist dealing with distinct aspects of the enemy assault without assistance from the other.

The Imperial Knight

Celestine seeks Medios to remove collars from Rem and Shera.

Celestine leads the group to Medios, a former magic colleague, to learn how to remove Rem and Shera's collars. Medios senses Krebskulm within Rem, but Shera mistakenly believes she is pregnant. Medios explains that a master can remove a collar by transferring magical energy into the slave's body. Diablo attempts this on Shera but stops due to embarrassment as the process is highly pleasurable for her. Later, Shera's brother Keera arrives to apologize for the bounty hunters and urges Shera to return home. She firmly refuses, prompting him to leave while claiming she will eventually return voluntarily.

Diablo and allies rescue Shera from Keera's hypnotic captivity and monster attack.

Diablo recalls childhood abandonment while crafting potions with Shera, who is then hypnotized by Keera’s flute and taken away. Depressed, Diablo is convinced by Rem and Alicia that Shera was coerced, prompting a rescue mission. Keera interrogates Shera in his tent, disbelieving her claims of innocence, and summons a slime to destroy her clothing before attempting assault. The group arrives after defeating his guards, but Keera hypnotizes Shera again to lie about wanting to stay with him. Diablo overrides this control using his authority as her master, forcing Shera to declare her desire to remain with Diablo and Rem. Enraged by this defiance, Keera summons a monster known as the Force Hydra to confront them.

Diablo defeats Hydra, Chester kills Keera, and Diablo wins against Chester.

Diablo destroys the Force Hydra by incinerating it, then agrees to spare Keera at Shera’s request. Chester arrives, beheads Keera, and captures defeated Elf troops while aiming to conquer Greenwood. He traps Diablo in an energy sphere and breaks Alicia’s sword during her defense of Shera. Diablo escapes and engages Chester in a closely matched battle, ultimately securing a narrow victory. Alicia threatens to report Chester’s unethical conduct to the King, forcing his surrender and troop withdrawal. The group uses potions to heal the Elf soldiers and consoles Shera regarding her brother’s death. Later, Sylvie gives Diablo an energy-restoring drink, but he becomes intoxicated, mistakes her for a body pillow, and caresses her, causing her significant embarrassment.

Shera trains with a Turkey Shot while the group prepares to remove Krebskulm from Rem at Starfall Tower.

During a meeting with the King, Alicia encounters Saddler, an arrogant Paladin investigating Diablo in Faltra City. Meanwhile, Shera bonds with a Turkey Shot, and Diablo instructs her on using the bird’s shared vision to enhance her archery skills. When Shera and Rem are bathing, Edelgard arrives to verify that Rem contains Krebskulm. After explaining the situation, Edelgard proposes a ritual at Starfall Tower in three days to safely extract the entity without harming Rem. Three days later, Alicia returns to warn the group about Saddler. Despite efforts to evade him, Saddler and his followers locate them. Saddler condemns Diablo’s companions for associating with a Demon Lord and injures Rem with magic. He attempts to petrify Diablo, but Diablo reflects the spell, turning Saddler to stone. The group then proceeds to Starfall Tower.

Diablo channels magic through Rem to summon amnesiac demon girl Klem who spares mortals

Edelgard instructs Diablo to transfer magical energy into Rem to release Krebskulm. He complies, resulting in a towering demon that transforms into a cute girl. The entity, now named Klem, has amnesia and refuses to destroy humanity after enjoying biscuits. Alicia opposes this decision, but Edelgard supports Klem. Fallen Eulerex attacks them, yet Edelgard and Diablo repel him. Approaching Faltra City, Edelgard departs because Fallen are unwelcome. Diablo becomes embarrassed when Shera and Klem rub against him to restore his energy. Alicia privately recalls her abusive past and desires the extinction of mortals. Meanwhile, Sadler regains his flesh and vows revenge.

Celestine learns of Klem's nature while Alicia betrays the group to Saddler.

The group informs Celestine about Klem, relieving her concern that the Demon Lord is evil. Separated from Shera and Diablo, Alicia betrays Rem and Klem to Saddler, leading to their arrest. Alicia intends to traumatize Klem to force a return to her original state. Saddler transports the captives to a church, planning to torture Rem into confessing to worshipping a Demon Lord. Meanwhile, Diablo and Shera search for the missing pair as a massive Fallen army advances on Faltra City. Klem attempts to protect Rem, but when Saddler attacks, Rem shields Klem and is impaled multiple times. Enraged, Klem reverts to her demon form, kills Saddler, and destroys the church. Diablo and Shera arrive as Klem begins to rampage.

Alicia joins Fallen forces while Diablo binds Klem and Rem forgives Alicia after her suicide attempt.

Alicia joins the army of Fallen as Edelgard, Eulerex, and she celebrate the return of the true Krebskulm. Shera treats Rem's injuries with potions while Diablo battles Krebskulm, damaging her significantly but failing to defeat her. Emile shields the girls from debris, allowing Rem to reveal she is unharmed, which causes Krebskulm to revert to the little girl Klem. The army of Fallen turns on Alicia for her failure, but Edelgard holds them off and urges her to escape. Sylvie attempts to kill Klem for the destruction caused, but relents when Diablo casts a spell to bind Klem to him as a slave, creating a collar that prevents disobedience. Later, Alicia appears and reveals she sneaked Edelgard, heavily injured from fighting off the other Fallen, into the city and begs Klem to heal her, which she does. Klem orders Edelgard to never kill mortals again. Rem asks Alicia why she did what she did and she reveals her past suffering and desire to wipe out the mortal races. Since Klem will not kill, Alicia attempts suicide, but Diablo stops her and tells her to find a new purpose to live for, then Rem forgives her. Diablo collapses in exhaustion and is embarrassed when all five girls strip and rub against him to donate magical energy. The next day, Edelgard disguises herself as a human and mingles with the people. Alicia leaves for a new journey. Shera and Rem ask Diablo choose one of them and kiss her, but he refuses, as he is a Demon Lord and only does what he wants.
